LABEIN Tecnological Centre, based in the Basque Country, has developed an innovative system for verifying tunnel safety in the case of fire. The new system, developed at the request of the Gipuzkoa Provincial Government, has been successfully tested in the new Lezarri (Bergara) tunnel on the A1 Eibar-Vitoria motorway.
The novel element in the testing set up by LABEIN, compared to other systems used to date, is that the verification can be carried out in a short period (about 8 hours) and without producing any deterioration or dirt in the tunnel.
The system, unheard of in Europe to date, is based on the use of equipment which generates hot (clean) gases which can emulate the smoke produced in a real fire both in terms of quantities and temperature. In this way, the behaviour of the gases when the tunnel’s ventilation system is activated may be studied, according to a pre-established programme.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
